Here is my comparison shot of before and after BERK HFCs. This chart only shows the HP gains so I will need to scan the sheet they printed for me to show you the TQ gains. Just so you know 13HP/6TQ gained. I will try to scan that in the next couple of days.

The interesting thing to note was that stock my Air/Fuel ration was peaking and dropping starting around 6000RPM. The Berk HFCs when ran cleaned up the Air/Fuel ration a ton. It is now relatively flat all the way up to redline. I wish I had a before printout of the Air Fuel ratio to show you guys but I will scan the sheet with the Berk in a couple days (hopefully).

The exhaust is definitely louder now. When they started my car after the install, I almost wanted to have them take the HFCs back off because it was really raspy but that cleared up after the HFCs were broke-in. I am glad about that.

 

there ya go buuuudddddyyyy ....lol

 

The funny thing Max is on the first run it gave 6HP more and I was like .... that's it? I was like well at least it sounds nice. Then they did the next run and it was 10HP and I was like that is more like it. Then the final run it was an increase of 13HP. I wish I would of done at least a couple more runs just to see where it equals out at. My runs without the HFCs were all very similar (within 1HP of each other). I am wondering it these HFCs can get me up to a 15HP average increase.

 

interesting.... maybe re dyno in a week? be up to 45hp + lol... but really maybe greater than 15...

 

This dyno chart looks the way it felt when I did my comparo drive. Between 5K& 7K RPM is where I felt the gains the most.

 

Ya, I am thinking about doing it again once they are broken in. I am going to be getting an exhaust soon (probably the FI if I can get the bigger tips) and that Injen intake if they perform like what has been announced. They were tuning a Evo9 at the shop before my dyno. The dude got 40+HP gain from just an intake and reflash on ECU. I want that from a Intake and ECU reflash....lol

 

I am waiting to see what Motordyne Engineering is going to release with regard to the 40 TQ and 10 HP claims on their future exhaust system.

 

Its not an exhaust system like you think....

 

Impressive gains.

 

bboy... I do wanna extend a public Thank You for Pre dyno and Post dyno to show a 3rd party true measurement... If more people did this we would know what works and what dont...

Thanks bro!

 

very cool...

my stock dyno increased each pull too

it was like 255, 259, 262

I can't wait to dyno again with the HFC's, i'm going to be doing 6 pulls to see how it goes.

 

so your comparing Max to max or AVG to AVG?

Great job though

 

I know this has been asked before but did you reset the ECU? please just bboy reply.

 

The dyno files the shop sent me....since you know these are fabricated.

*The last part of the comment was sarcasms for the people here that cannot tell the difference.

I added the .txt extention so I could upload the files. When you download them you will need to remove the .txt extention and if you have your system up to show all file extentions then that will change it back to a .drf file. You will then need to download the reader from http://www.dynojet.com/downloads/software.aspx to read the file. I copied the file to another location, renamed it, then changed it back, and it opened fine for me so it should do the same for anyone else.

 

You should put a note in there that this was also dynoed using the wrong gear, much like the first one. People are gonna start thinking we're weak sauce cause your dyno graph is so low. The inconsistency of each run is puzzling. Makes this much less trust worthy. Thank you for the dyno results none-the-less.
